First, I'm sorry if this is not the place to create this topic, but I think is the better place to do it.
I'm trying to create my first Listener, but I'm don't have any knowledge on Perl, so i need some explanations, or ideas to implement it.
Problem: There are many SPAM emails in INBOX folder after Spamassasin catalog them with X-Spam-Flag = YES
Solution: To add a small filter in dovecot to move them to Junk folder.
In order to do this, I need to change some parameters in /etc/dovecot/dovecot.conf
To add "sieve = /etc/dovecot/sieve/default.sieve" inside plugin context:
To modify mail_plugins inside protocol lda, but not mail_plugins line above the document.
Finally, to create this document with vmail:mail permissions on /etc/dovecot/sieve/default.sieve
Basically, I'm trying to do for myself looking other listeners, but I don't understand pretty well and I don't know how to add a line inside a context, how to replace mail_plugins line, when I have 2 different on the document, and I don't know how to create a document with permissions.
Thank you in advance for your help.
